Resource allocation signaling for slot aggregation
There is disclosed a method of operating a network node in a Radio Access Network. The method includes transmitting a downlink control information message, the downlink control information message having a slot allocation indication and a symbol allocation indication. The slot allocation indication indicates a slot aggregation having a plurality of slots being allocated for communication to at least one user equipment, each slot including a plurality of symbols. The symbol allocation indication indicates allocation of symbols to at least one channel according to an allocation pattern for two or more of the plurality of slots. The disclosure also pertains to related methods and devices.
1. A method of operating a user equipment in a New Radio, NR, Radio Access Network, the method comprising:
transmitting signaling on a Physical Shared Uplink Channel, PUSCH, utilising a slot aggregation, the slot aggregation being allocated by a slot allocation indication and a symbol allocation indication in a received downlink control information (DCI) message;
the slot allocation indication comprising:
a bit pattern indicating a number of a plurality of slots within the slot aggregation, the indicated number of the plurality of slots being allocated for the transmitting signaling on the PUSCH utilising the slot aggregation, each slot comprising a plurality of symbols,
the slot allocation indication further comprising a slot location indication, the slot location indication indicating an offset value, the offset value indicating a location of a starting slot for the slot aggregation and the offset value being semi-statically configured; and
the symbol allocation indication comprising:
a bit pattern indicating a pattern of symbols allocated to the PUSCH according to an allocation pattern for the indicated number of the plurality of slots,
the bit pattern indicating a starting symbol and a number of symbols in the pattern of symbols, the pattern of symbols being allocated for one slot and repeated in each slot of the indicated number of the plurality of slots within the slot aggregation, and
the slot allocation indication and the symbol allocation indication being included in a time-domain resource allocation field in the DCI message.
2. A user equipment for a New Radio, NR, Radio Access Network, the user equipment comprising:
radio circuitry; and
processing circuitry and the user equipment being configured to utilise the processing circuitry to cause the radio circuitry to:
transmit signaling on a Physical Shared Uplink Channel, PUSCH, utilising a slot aggregation, the slot aggregation being allocated by a slot allocation indication and a symbol allocation indication in a received downlink control information (DCI) message;
the slot allocation indication comprising:
a bit pattern indicating a number of a plurality of slots within the slot aggregation, the indicated number of the plurality of slots being allocated for the transmitting signaling on the PUSCH utilising the slot aggregation, each slot comprising a plurality of symbols,
the slot allocation indication further comprising a slot location indication, the slot location indication indicating an offset value, the offset value indicating a location of a starting slot for the slot aggregation and the offset value being semi-statically configured; and
the symbol allocation indication comprising:
a bit pattern indicating a pattern of symbols allocated to the PUSCH according to an allocation pattern for the indicated number of the plurality of slots,
the bit pattern indicating a starting symbol and a number of symbols in the pattern of symbols, the pattern of symbols being allocated for one slot and repeated in each slot of the indicated number of the plurality of slots within the slot aggregation, and
the slot allocation indication and the symbol allocation indication being included in a time-domain resource allocation field in the DCI message.
3. A network node for a New Radio, NR, Radio Access Network, the network node comprising:
radio circuitry; and
processing circuitry and the network node being configured to utilise the processing circuitry to cause the radio circuitry to:
transmit a slot allocation indication and a symbol allocation indication in a downlink control information (DCI) message to a user equipment, the slot allocation indication and the symbol allocation indication in the downlink control information message allocating a slot aggregation to a user equipment;
the slot allocation indication comprising:
a bit pattern indicating a number of a plurality of slots within the slot aggregation, the indicated number of the plurality of slots being allocated for transmitting signaling on a Physical Uplink Shared Channel, PUSCH, utilising the slot aggregation, each slot comprising a plurality of symbols;
the slot allocation indication further comprising a slot location indication, the slot location indication indicating an offset value, the offset value indicating a location of a starting slot for the slot aggregation and the offset value being semi-statically configured; and
the symbol allocation indication comprising:
a bit pattern indicating a pattern of symbols allocated to the PUSCH according to an allocation pattern for the indicated number of the plurality of slots,
the bit pattern indicating a starting symbol and a number of symbols in the pattern of symbols, the pattern of symbols being allocated for one slot and repeated in each slot of the indicated number of the plurality of slots within the slot aggregation, and
the slot allocation indication and the symbol allocation indication being included in a time-domain resource allocation field in the DCI message.
